Heather plant named &#34;Red Pacifica&#34;

ABSTRACT

The present invention relates to a new and distinct cultivar of Heather plant named `Red Pacifica`, believed to be a seedling of Erica regerminans `Pacifica` (U.S. Plant Pat. No. 5,430) and of unknown pollen parent, discovered growing in a field of Erica regerminans `Pacifica`, where it was selected because of its distinctive Magenta-Pink color, larger growth habit and slightly earlier blooming time.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of the Ericaceaefamily which has been named Erica `Red Pacifica`. This new heathervariety was discovered by me at my commercial nursery in Watsonville,Calif. It was discovered as a seedling growing in a cultivated field ofErica regerminans `Pacifica` (U.S. Plant Pat. No. 5,430), the varietybelieved to be the seed parent. The pollen parentage is unknown. It wasnoticed because of its distinctive magenta-pink color, its taller growthhabit and earlier blooming time than the seed parent `Pacifica`. I amnot able to determine the species affiliation of the `Red Pacifica`.

Since my discovery of this new plant, I have reproduced it throughsuccessive generations by means of cuttings and have found that itsdistinctive color, size and blooming time remain true from generation togeneration and appear to be firmly fixed. This variety is now beinggrown for the commercial marked at my nursery which is located along thetemperate Central California coast.

`Red Pacifica` is a regerminans-type heather and resembles its oldestancestor Erica regerminans, a variety in commercial production for manydecades, in its overall shape of the plant, size and shape of the bloomsand the way they are borne on the stems.

The closest commercial cultivar to my new variety, of which I am aware,is the Erica regerminans `Pacifica`, discovered by me several years ago.The characteristics which distinguish the new cultivar from Ericaregerminans `Pacifica` are as follows:

1. `Red Pacifica` begins to bloom in mid-September, and blooms two (2)weeks earlier than `Pacifica`;

2. `Red Pacifica` has a more vivid, deeper magenta-pink color than`Pacifica`; and

3. The stems of `Red Pacifica` average 6 inches more in length than`Pacifica` making the plant height significantly taller.

The new cultivar, `Red Pacifica`, can also be distinguished by thefollowing characteristics from another of the regerminans-type heathers,the cultivar `Augustina` (U.S. Plant Pat. Ser. No. 07/393,674),discovered and propagated by me: `Red Pacifica` begins to bloom aboutfour (4) weeks after `Augustina`, and `Red Pacifica` is a paler pinkcolor than `Augustina`.

The discovery of these new heathers with different blooming times, givesthe commercial grower the ability to provide the flower industry withregerminans-type heather in bloom continuously from mid-August throughNovember; starting with `Augustina` blooming in mid-August andcontinuing successively with `Red Pacifica` blooming next aroundmid-September, `Pacifica` next around early October, and ending with theregerminans blooming in early November.

The original `Red Pacifica` plant came from seed and I presume it isalso capable of producing seed. I have not looked for any seed since Ipropagate `Red Pacifica` by cuttings. `Red Pacifica` is resistant topowdery mildew and verticillium wilt, but sensitive to phytophthora andpithium.

DESCRIPTION OF THE DRAWINGS

The accompanying drawings serve by color photographic means, toillustrate the new plant variety, `Red Pacifica` in comparison to itsclosest known commercial variety, Erica regerminans `Pacifica`. Theupper view is a color photograph of a close up view of a stand of thenew variety growing in the field which shows fully opened blooms of thenew variety together with buds of the new variety in early stages ofbloom maturity. The lower view is a color photograph which shows a fieldof three different varieties of Heather. The green plants on the rightare the variety Erica persoluta `Sunset` (U.S. Plant Pat. No. 5,336),the blooming plants in the center show a row of my new variety in fullbloom on the right, and a row of `Pacifica` almost in full bloom on theleft. The lower photo shows the taller growth habit of my new variety,and both photos illustrate the overall appearance of my new variety.Both photo drawings were taken on Oct. 5, 1989 at my commercial nurseryin Watsonville, Calif.

DETAILED DESCRIPTION OF THE DRAWINGS

The following is a detailed description of my new Heather plant, Ericaregerminans `Red Pacifica`, based upon observations of field-grownplants in October 1989 at Watsonville, Calif. The color terminology usedin the following is in accordance with the Royal Horticultural SocietyColour Chart, the color specified being as close as could reasonably bedetermined from the very small flowers of this plant. I chose a colorwhich averages the shades of magenta-pink found on each bloom.

PLANT

Origin: Seedling.

Parentage:

Seed parent.--Erica regerminans `Pacifica` (U.S. Plant Pat. No. 5,430).

Pollen parent.--Unknown.

Classification:

Botanic.--Erica regerminans `Red Pacifica`.

Commercial.--Red Pacifica Heather.

Form: Woody shrub, perennial.

Shape: Generally upright with stems curving slightly to accommodatefullness of plant.

Height: Two and one-half feet.

Main stem length: Twenty-four inches.

Branching: Generous, pruned yearly to encourage fullness.

Growth: Vigorous with medium strength.

Foliage: Abundant, tiny needle-like leaves most dense on flower bearingbranches of main stem.

Size of leaf.--1/8 to 1/4 inch.

Shape.--Long, and very narrow.

Color.--Mature foliage dark green (R.H.S. 139A).

Texture.--Smooth.

THE BUD

Size: 1/8 inch or less diameter. 3/16 inch or less length.

Shape: Tear-drop with rounded base resting in calyx.

Color: R.H.S. 70C.

Rate of opening: Progressive and continuous beginning at base of stemand progressing rapidly upwards to tip.

INFLORESCENCE

Blooming habit: Once annually, early fall beginning mid September to theend of October.

Size of bloom: Averages 1/8" in diameter and length.

Borne: Compound raceme. Clusters with as many as 12 terminal buds.

Shape: Bell-shaped with pinched opening.

Appearance: Satiny.

Color: Magenta-pink, R.H.S. 70C.

Flower stem:

Length.--1/4 to 6 inches.

Color.--Light brown.

Strength.--Woody and supple.

Fragrance: Mildly wild.

Branching: Upright and about 45 degree angle from main stem.

Lasting quality:

On plant.--2 months (approximation).

As cut flower.--Up to 4 weeks (approximation).

Discoloration: Slight deepening of color after full bloom.

Persistence: The bloom persists long after the stem ceases to drawwater. Blooms do not shed easily.

Effects of weather: Plant can tolerate freezing temperatures for severalhours, but can be damaged by prolonged cold. Temperatures of 90 degreesF.+ can stress the plant. Extended periods of hot, dry weather willaccelerate the rate of blooming and can cause blooms to fade and declinemore quickly. Extended wet weather causes mature blooms to turn brown.

I claim:
 1. A new and distinct cultivar of Heather plant named `RedPacifica`, substantially as herein shown and described characterizedparticularly as to novelty by its distinctive Magenta-Pink color, tallergrowth habit and slightly earlier blooming habit than its seed parentErica regerminans `Pacifica`.
